Arrow Windshield Defroster - Supposed To Be Hot Air or Cold Air?

Got my car back from the shop from the accident (pictures to be posted soon in a different thread).

Had to use the windshield defroster a couple days ago.
After pressing the button, the air went on full blast but was on "LO" temperature rather than the usual "HI" heat.

Any idea how to fix it? Or what may have caused it to change?

On every Benz I've ever owned / driven, the windshield defroster would always blow out "HI" heat air on full blast.

Any ideas?

Is the A/C led on? Is the MAX A/C also on? Rolling computers so if all else fails try pulling the plug.

A/C is on. Not the Max A/C.
It's the first time it's ever done that and continues to do it.

Planning to have the entire system re-calibrated on Monday. Hopefully that resets what it needs to.

Update -
System checked out with no fault codes whatsoever.
Windshield defroster has to be manually set to "HI" heat, instead of it automatically changing on its own just by pressing the button.

Anyone know a way of getting it back to normal?
